Hey all, I am VERY new to this hobby, and I am looking at purchasing a Brinkmann Trailmaster offset smoker. In reading about the various mods and what not I have a few questions: 1) People talk about using lava rocks to distribute heat and evening out the temperature. Is that in place of a tuning plates? Or used in conjunction with tuning plates? 2) Does anyone have any experience or feedback on the baffle/plate from BBQ Smoker Mod? Does do a good job? http://www.bbqsmokermods.com/product-p/br-hor-tune.htm I appreciate any feedback.
